XL-009 User Configuration And Preferences System For TriptaFittings-FreeCAD

Hey guys! Let's dive into the details of Issue XL-009: Sistema de configuración y preferencias, which is all about setting up a user-friendly and customizable system for our TriptaFittings-FreeCAD plugin. Currently, there's no configuration system in place, which means users can't tweak the plugin's behavior to their liking. This article will cover the identified problems, the proposed solution, specific tasks, acceptance criteria, and an estimated timeline. Let’s get started!

Descripción del problema

The Current State of Affairs

Right now, the plugin lacks a proper configuration system. This means a one-size-fits-all approach, which, as we all know, isn't ideal. We need to empower our users to personalize their experience, tailoring the plugin to their specific needs and workflows. Think of it like trying to drive a car without adjusting the seat or mirrors – doable, but definitely not comfortable or efficient!

The absence of a configuration system touches several key areas. We're talking units, standards, export options, and validation processes. Each of these needs its own set of customizable settings to make the plugin truly shine. Without these, we're missing out on a significant opportunity to enhance user satisfaction and productivity. So, what exactly are the pain points?

Key Issues Identified

Let's break down the specific problems we've pinpointed:

• ❌ No hay configuración de unidades (No Unit Configuration): Currently, users can't select their preferred units (e.g., millimeters, inches). This is crucial for precision and consistency in design.
• ❌ No hay preferencias de usuario (No User Preferences): There's no way to save personal preferences, making each session a reset to the default settings. Annoying, right?
• ❌ No hay configuración de estándares (No Standard Configuration): The plugin doesn’t allow users to choose specific industry standards (like DIN, ANSI, ISO). This limits its applicability in diverse projects.
• ❌ No hay configuración de exportación (No Export Configuration): Users can't customize export formats (STEP, DXF, etc.). Different projects require different formats, so flexibility is key.
• ❌ No hay configuración de validación (No Validation Configuration): There’s no way to adjust validation settings, which means users can't control how strictly the plugin checks for errors.

These issues collectively highlight the need for a robust configuration system. It’s not just about adding features; it’s about making the plugin more adaptable and user-centric. So, what’s the plan to fix this?

Solución Requerida

The ConfigurationManager Class

To tackle these problems, we need a systematic approach. The proposed solution involves creating a ConfigurationManager class in Python. This class will handle loading, saving, and managing the plugin's configuration settings. It’s like the control panel for our plugin, giving users the power to adjust various parameters.

The ConfigurationManager class will use a JSON file (triptafittings_config.json) to store the configuration settings. JSON is a lightweight and human-readable format, making it perfect for this purpose. Here’s a peek at how the class will work:

class ConfigurationManager:
    def __init__(self):
        self.config_file = "triptafittings_config.json"
        self.default_config = {
            'units': 'mm',
            'standards': ['DIN_32676_A'],
            'export_formats': ['STEP', 'DXF'],
            'validation_level': 'strict',
            'auto_backup': True,
            'backup_interval': 24,  # hours
            'simulation_enabled': False,
            'documentation_language': 'en'
        }
        self.load_configuration()
    
    def load_configuration(self):
        """Carga configuración desde archivo"""
        try:
            with open(self.config_file, 'r') as f:
                self.config = json.load(f)
        except FileNotFoundError:
            self.config = self.default_config.copy()
            self.save_configuration()
    
    def save_configuration(self):
        """Guarda configuración a archivo"""
        with open(self.config_file, 'w') as f:
            json.dump(self.config, f, indent=2)
    
    def get_setting(self, key: str, default=None):
        """Obtiene valor de configuración"""
        return self.config.get(key, default)
    
    def set_setting(self, key: str, value):
        """Establece valor de configuración"""
        self.config[key] = value
        self.save_configuration()

Key Functions Explained

Let's break down what each function does:

• __init__(self): This is the constructor. It initializes the config_file attribute with the name of the configuration file, sets up the default_config dictionary with default settings, and calls load_configuration() to load settings from the file.
• load_configuration(self): This function tries to load the configuration from the JSON file. If the file doesn’t exist (FileNotFoundError), it uses the default_config and saves it to a new file.
• save_configuration(self): This function saves the current configuration to the JSON file. It uses json.dump() to write the dictionary to the file with proper indentation for readability.
• get_setting(self, key: str, default=None): This function retrieves a setting by its key. If the key is not found, it returns the provided default value.
• set_setting(self, key: str, value): This function sets a configuration value for a given key and then saves the configuration to the file.

With this class in place, we can easily manage and persist user preferences. But how do we make these settings accessible to the user?

Tareas Específicas

The To-Do List

To get this configuration system up and running, we have several tasks to tackle. These tasks cover everything from the core implementation to the user interface elements. Here’s a rundown:

• [ ] Implementar sistema de configuración (Implement Configuration System): This involves creating the ConfigurationManager class and ensuring it can load, save, and manage settings.
• [ ] Crear interfaz de preferencias (Create Preferences Interface): We need a user-friendly interface where users can adjust their settings. This could be a dialog box within the FreeCAD plugin.

• [ ] Crear configuración de validación (Create Validation Configuration): This involves setting up different levels of validation (strict, lenient, etc.) so users can control how rigorously the plugin checks for errors.

Each of these tasks is crucial for a comprehensive configuration system. But how will we know if we've succeeded?

Criterios de Aceptación

How We'll Measure Success

To ensure we’ve nailed it, we need clear criteria for acceptance. These criteria will help us verify that the configuration system is working as intended and meets user expectations. Here’s what we’re aiming for:

• [ ] El sistema de configuración es persistente (The Configuration System is Persistent): Settings should be saved and loaded correctly, so users don’t have to reconfigure every time they use the plugin. This means the save_configuration() and load_configuration() functions in our ConfigurationManager class need to be rock solid.
• [ ] La interfaz de preferencias es intuitiva (The Preferences Interface is Intuitive): The user interface for adjusting settings should be easy to navigate and understand. No one wants to wrestle with a confusing settings panel!
• [ ] La configuración de unidades funciona correctamente (Unit Configuration Works Correctly): When a user selects a unit, the plugin should accurately reflect that choice in its calculations and displays. This is critical for precision.
• [ ] La configuración de estándares es flexible (Standard Configuration is Flexible): Users should be able to select multiple standards and switch between them easily. The system should accommodate various industry practices.
• [ ] La configuración de exportación es completa (Export Configuration is Comprehensive): Users should be able to choose from a range of export formats to suit different project requirements. This ensures compatibility with other software.
• [ ] La configuración de validación es robusta (Validation Configuration is Robust): Different validation levels should provide appropriate checks without being overly restrictive or too lenient. This helps users catch errors without unnecessary hassle.

Meeting these criteria will ensure we’ve built a configuration system that’s not only functional but also user-friendly and reliable. So, how much time will all this take?
